Buck regulator offers a thermally enhanced 3mm x 3mm DFN package

Alpha and Omega Semiconductor Limited (Sunnyvale, CA) announced the release of the fifth-generation EZBuck with the AOZ3103, a high-efficiency, simple-to-use synchronous buck regulator, with an operating input voltage range from 4.5V to 18V and the ability to supply 3A of continuous current. The device offers a low on-resistance power stage in a thermally enhanced 3mm x 3mm DFN package, allowing cooler power conversion for a variety of consumer electronics applications such as LCD TVs, set-top-boxes, as well as DVD players and recorders. Other features include:

• FET on-resistance (typ) for high-side of 80mOhms and 30mOhms for the low-side.
• Switching frequency of 500KHz.
• Feedback tolerance of +/- 1.5%.
